In this paper, the developed formulation, which we shall call the “reference” one, is used to assess the validity of the most popular simplified approach for the calculation of the lightning electromagnetic field over a conducting earth, namely, the Cooray ...
Radio frequency geophysical methods are known for being very versatile tools in ground- and groundwater investigation at shallow depths. They are fast and easy to use and allow a high density of information over large surfaces, which makes them very suitab ...
This paper describes a low power Ultra-Wideband Impulse Radio (UWB-IR) Application Specific Integrated Circuit (ASIC) transmitter implemented in UMC 0.18 μm. This transmitter has been designed for low data rate communication applications and indoor positio ...
We propose an algorithm for very high-resolution satellite image classification that combines non-supervised segmentation with a supervised classification. Both multi-spectral data and local spatial priors are used in the Gaussian Hidden Markov Random Fiel ...
